Dark matter could be made of black holes from the beginning of time

"The method will become more accurate as more gravitational wave detections are made, Takhistov said: "The test is statistical in nature, so gathering more data will allow for a better understanding."

Interesting testing. Will have to wait and see what develops but too many primordial black holes *in the beginning* could have other problems introduced in the early, smaller size universe :) The paper link provided is very useful. https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.126.071101

Looking at black holes that could be 1 to 2.5 solar masses or so.

Dark Matter is everywhere, therefore, we can create a catalog of everything everywhere and list them as potential sources of Dark Matter. Every detectable object (matter-energy) is a consequence of Dark Matter.
